My original post on the subject was purely hypothetical that Golfs can now cost the same as a base model Porsche new.
I very much agree with your point you need to pay more to save more in the long run when buying specialist cars like Porsches and hence my comparing how second hand Caymans can actually have lower monthly PCP costs than late second hand Golf R’s and Clubsports due to stronger residuals. I was actually using the Porsche UK used car selection rather than looking at independent sellers as the handy PCP calculator meant I could do direct comparisons between VW UK approved used and Porsche approved used.
I honestly don’t know what I’d buy with an £80k budget, I’ve never put myself in that position or thought about it. To me a large sum like £80k would go into property. I’m incredibly dull I’m afraid and have never had much ambition so expensive cars have always been something other people buy, my bar is set far lower.
I’d definitely not spend it on a 2.0 Cayman though!

I doubt you’d get a 4.0 one for that(?)
£40k budget, I can remember not so long ago Audi dealers were knocking out vanilla RS3’s brand new for around that towards the end of the last generation. I did have a serious think about it at the time.
What does £40k buy now? Not so much I’d guess.
I paid £33k for my Clubsport 19 months ago, so I don’t think I’d stomach paying £40k for one now. If I was going over £40k on a Golf I’d push the boat a bit further and get an R with a few extras.
I’m not sure what I’d go for with a circa £40k budget to be honest. Nothing much floats my boat. Maybe I should do a bit of car window shopping, trouble is I tend to end up putting my money where my mouth is and inadvertently buy something. So a bad idea. I’m quite settled with my 8CS which is a rarity for me.
How much does a mint low mileage Clubsport S go for these days?
